Insert Sheets
This allows you to to enter multiple sheets before or after the sheet you specify on the list. Besides not having to add sheets one at a time, you will find it easier to do it from a list than try to navigate to the right sheet using the sheet tabs.
Select Specifc Sheets
This allows you to select multiple sheets. As above, doing it from a list is easier than using the sheet tabs.
Reset Built-In Toolbars
This is only available with the 2007-2010 version of the utilities and will reset all built-in toolbars. You will find it in Developer Tools, along with the other toolbar and control tools available.
Cell Menu
I've also made some small improvements to the cell menu. I noticed that the Camera tool men item sometimes "multiplied" so I edited the code to stop this from happening.
